ColorSketch: A Drawing Assistant for Generating Color Sketches from Photos

Area of Science:

• Computer graphics
• Human-computer interaction
• Digital art

Background:

• Traditional color sketching requires artistic skill and time.
• Digital tools often limit user control, hindering expressiveness.
• Generating appealing color sketches from photographs is challenging for novices.

Purpose of the Study:

• To develop an interactive system, ColorSketch, for assisting users in generating color sketches from photos.
• To balance user control over artistic elements with automated augmentation for enhanced results.
• To evaluate the system's effectiveness, particularly for novice users.

Main Methods:

• Developing an interactive drawing system integrating user input with automated processes.
• Implementing algorithms for color mapping, brush stroke rendering, and blank area creation.
• Conducting experiments and user studies to assess system performance and usability.

Main Results:

• Users, especially novices, demonstrated improved ability to create color sketches using ColorSketch.
• The system successfully augmented user-drawn pencil sketches with color and rendering.
• Qualitative feedback indicated user satisfaction with artistic control and output quality.

Conclusions:

• ColorSketch effectively assists users, particularly novices, in creating compelling color sketches.
• The system's approach preserves artistic freedom while leveraging automation for enhanced results.
• Interactive systems can bridge the gap between user intent and artistic execution in digital media.
